Question

所以，我意识到有多个线程在询问这类问题，但它们都没有真正描述我遇到的那种错误。

我在这里创建我的变量并设置我的方法：

IBOutlet UIButton *BuildNewTower;
IBOutlet UIButton *CancelTower;

-(IBAction)BuildNewTower:(id)sender;
-(IBAction)CancelTower:(id)sender;

然后我在主类中调用这些函数，如下所示：

-(IBAction)BuildNewTower:(id)sender{
if(credits >= 15){
    BuildNewTower.hidden = YES;
    CancelTower.hidden = NO;

    Tower1S.hidden = NO;
    Tower2S.hidden = NO;
    Tower3S.hidden = NO;
    Tower4S.hidden = NO;
    Tower5S.hidden = NO;
    }
}

-(IBAction)CancelTower:(id)sender{
BuildNewTower.hidden = NO;
CancelTower.hidden = YES;

Tower1S.hidden = YES;
Tower2S.hidden = YES;
Tower3S.hidden = YES;
Tower4S.hidden = YES;
Tower5S.hidden = YES;
}

粗略地总结一下，BuildNewTower和CancelTower按钮不会对它们继承的.hidden变量做出反应。所有其他对象（所有ImageViews）确实会消失。

我猜这可能与按钮有关，而且它们被隐藏了？
